TRANSOlVl-LIFTER.

` SPECIFICATION forming part of Letters Patent No. 381,742, dated April24,1888.

l Application led October 27, 1887. Serial No. 253,550. (No model.)

To all whom, it may concern:

Be it known that I, JOHN F. WoLLENsAK, acitizen of the United States,residing at Chicago, Illinois, have invented certain new and usefulImprovements in Fasteners for Transom-Lifters, of which the following isa speciication.

The object of my invention is to make a fastener for the lifting-rod oftransoms and other` articles in which the nut cannot be removed withoutdifficulty; and my invention consists in the features and details ofconstruetion, hereinafter described and claimed.

In the drawings, Figure 1 is a planview of my improved lifter with thenut and other parts in place. Fig. 2 is a longitudinal section of thefastener, taken in the line Y Y of Fig. 3. Fig. 3 is a section of theshell or case of the fastener, taken in the line X X of Fig. 1. Fig. 4is a perspective view of the Washer used in Figs. 1, 2, and 3, viewedfrom the inside. Fig. 5 is afastener employing a modified washer. Fig. 6is a longitudinal section of the same, taken through the line Y Y ofFig. 7. Fig. 7 is a longitudinal section taken through the line X X ofFig. 5. Fig. 8 is a perspective view of the shell or case used in Figs.5, 6, and 7; and Fig. 9 is a perspective view of the washer used in suchfigures.

A represents the shell or case of the fastener; B, a flange or foot bywhich it is attached or screwed to the door-jamb; C, the liftingrodofthe transom; D, awasher between the top of the shell or case and thefastening-nut; d, a projection on such washer; E, the fastening-nut; e,an" extension ou the same; F, a square hub on the washer used in Figs.1, 2, and 3; G, a square socket in the top of the shell or case in whichsuch hub rests; H, a square socket in the washer used in Figs. 5, 6, 7and 8, and I a square hub on the shell or case fitting into such squarehole or socket.

In making my improved fastener as shown in the firstfour figures of thedrawings, I make a shell or case in which the different parts are to bearranged and provide it with a flange or foot to enable it to be screwedor otherwise securely attached to a door-casing.

As my improvement does not consist in this foot or flange or in themethod of attaching the shell to the door-casing, I do not speciallyemphasize these matters, as various other means may be employed in theirplace. The shell or case is provided with holesl through its sides topermit the lifting-rod of a transom or other article in connection withwhich it is to be used to be passed. In using my fastening device with atransom-lifter these holes would naturally be at the top and bottomsides of the shell or case. Of course it is understood that the shell orcase is hollow, as shown in the figures of the drawings. A short rodwith a hook, ring, or eye on its inner end to wholly or partiallyencircle the lifting-rod is inserted from the inside of the shell orcase with its end extending out and threaded, so as to receive afastening-nut. For convenience I will term this short piece thefastening device and designate it by the letter J. Instead of providingthe end of the shell or case with a round hole out of which the threadedend of the fastening device may eX- tend, I provide it with a squarehole or socket, and I make a washer, D, which is provided with a squarehub adapted to fit into the square hole or socket in the end of theshell, so that it cannot be rotated. This washer is provided with around hole through'which the threaded end of the fastening deviceextends, as shown in Fig. 2, and is provided with an outwardlyextendingprojection, d, as shown in Fig. 1. The fastening-nut is properlythreaded to permit its being screwed onto the threaded end of thefastening device, and its inner side is provided with an extension, e,adapted to contact with the projection d when nearing the washer D.-

In operating my fastener, as shown in the rst four figures of thedrawings, I insert the square hub of the washer D in the square hole orsocket provided for4 it in the outer end of the shell or case. I theninsert the fastening device from the inside, with its threaded endextending out through t-he holein the washer. I then put on thefastening-nut and run it down until the extension e passes theprojection d the last time, with the fastening device dra'wn out againstthe washer. Immediately after the extension has passed the projectionthe last time I push the fastening device, with its nut, in, so as tobring the hook or eye on the inner endof the fastening device in linewith IOC the holes of the shell or case. This of course brings theextension e down far enough to cause it to strike against the projectiond upon reversing the nut and prevent the removal of the nut. The liftingrod is then inserted through the holes of the shell or case and throughthe ring, hook, or eye on the inner end of the fastening device. Thefastening-nut is then turned forward until the liftingrod is drawnsufficiently tight against the sides ofthe holes in the shell or case,as shown in Fig. 1, to prevent its being moved up or down until the nutis loosened and the friction released.

In Fig. 5 and following figures I have shown a modification of myfastener. Instead of providing the washer with a square hub to fit intoa square hole or socket in the end of the shell or case, I provide theend of the shell or case with a square hub, as shown in Fig. 8, andprovide the washer with a square socket, as shown in Fig. 9,- adapted tofit over the hub on the shell or case and prevent its rotation. Thismodification is a mere reversal or transposition of these features, asalready described in connection with the first four gures of thedrawings. Instead of using the fastening device as already described, Ibring the edges of -the washer D down outside of the shell or c ase, asshown in Figs. 5 and 6, far enough to bear against the lifting-rod andpress it securely against the inner edges of theholesin the shell orcase, as shown in Fig. 5. This arrangement enables me to dispense withthe fasten ing device, and in its place the end of the shell or case isextended and threaded to receive a fasteningnut, as shown in Figs. 6 and8. In operating this modified form of fastener I place the washer ontothe shell or case with its square socket fitting around the square hubon the end of the shell. I run the fasteningnut down until the extensione passes the projection d for the last time, when the washer is pusheddown as far as it will go with the lifting-rod out of the shell or case.When the extension has thus passed the projection for the last time, Idraw the washer out enough to insert tlie liftingrod. This brings theprojection on the washer in the way of the extension on the nut, so thaton reversing the nut the two will contact with each other and preventthe removal of the nut. The nut is then run down and the edges of thewasher forced tightly against the lifting-rod, so as to hold it by thefriction thus created between the two parts, as shown in Fig. 5.

It is necessary that, after the rod is in place and has pushed thewasher out so that the projection on the washer and the extension on thenut cannot pass each other, the nut should sufficiently tighten theparts before the projection and extension come into contact again by acomplete turn of the nut. If this should not be the case, the washer maybe turned a quarter or a half farther around, so as to permit the nut tobe turned also a quarter or a half farther. In this way in putting theparts together their positions may be regulated and adjusted, and whenthe parts become worn they may be again adjusted so' as to secure thenecessary friction between the washer anhd the lifting-rod. Thisadjustment can also be effected with the arrangement shown in the firstfour figures of the drawings.

I have spoken of the washers and the shells or cases being provided withsquare sockets and square hubs. As the only object of having them squareis to prevent their rotation when put together, any other angular formor means of preventing rotation would obviously answer the same purpose.I do not mean, therefore, to emphasize these forms and means, but simplyto limitmyself to washers and shells so connected together as to benon-rotatable with respect to each other. This nonrotation could be aswell secured by making a square orl angular hole through the washer anda correspondingly square or angular portion on the stern of thefastening device shown in Fig. 2; or the washer, as shown in the variousfigures, could be extended down on the outside of the shell or case topartially surround or embrace the lifting rod. In this case the washershown in the first four figures would have to have its edges turned overthe outer end of the shell or case and brought down enough for thepurpose, while the washer shown in the remaining figures would simplyneed to have its depending edges somewhat hollowed out to partiallyencircle the liftingrod. I mention these as illustrations of the ways inwhich non-rotatability between the washer and the shell can be obtained.I have also mentioned my improvements in connection with atransom-lifter; but I mean to employ them in connection with otherdevices where it is required to hold a rod in any fixed position. Inusing the term transom-lifter or in speaking of the square sockets orsquare hubs either in the specitcation or in the claims I mean to usethese terms in the broad sense above explained.

XVhat I regard as new, and desire to secure by Letters Patent, -isl. Ina fastener for transomlifting rods, the combination of a shell or casehaving holes in its sides through which the lifting-rod may pass, awasher engaging non-rotatably with the outer end of the shell or caseand having a projection, as d, a lifting-rod passing through the holesin the shell or case and held in a fixed position when the fastening-nutis screwed down, and a fastening-nut having an extension, as c, theextension on the nut and the projection on the washer engaging with eachother as the nut is unscrewed and preventing its removal when the partsare together, substantially as described.
